TAPI Settings wont save

We are using a voip Shoretel phone system. When I installed the Shoreware Director (voip software) in compatibility mode, it installed correctly. Now when I go into Control Panel > Phone and Modem Options > Advanced Tab, there is a "Shore Tel Remote TAPI Service Provider" None of the settings will save when I enter in voip server...etc...

I know this is probably an issue with Shoretel, and they wont support it for a while, but just seeing if anyone has any experiences or suggestions with it....

Reinstall it, reboot. Go through the normal user setup process. When finished, close pcm (right click, exit all). In the Call Manager program files folder, run vistatapifix.exe. Make sure to run as administrator. Open pcm and all will work.
